This is precisely what should be established, defined and set in stone before advertising existence (or even idea) of community. Otherwise there will be a lot of very surprised people coming to you for drugs and sex 
I wish I could say there is hope, but the longer I live the longer it seems “it won’t end up with what you want” anyway. 99.99% guaranteed.
Also… the advantage of a company is that you get to go home after work. Even if the “work” is what you love, you will get at some point bored and want to get away.
And yet another thing that crossed my mind, I find the idea of “nests” (Stranger in a Strange Land) much more appealing. You don’t need to live there (unless you want to), but you know there is a place that you belong to. Many places. Distributed community
And last but not least,
Definitely, and virtual community should use all available comms, text being an option, but mainly video conferences… that’s level up from convenient text-based anonimity. Say, if there was a weekly video chat just to see if it makes sense… Evening, like 8PM GMT, middle of the week, like thursday? Technology to be determined, google hangaout I used in the past and it worked. Or join.me, or… something?
